The highest quality
mulberry silk & organic cotton

The inside of our boxerbrief is made of mulberry silk from India. This silk is softer than any other type of silk (or textile), 100% organic, odorless and hypoallergenic. In normal English: our boxer briefs know a super soft touch and offer a small chance of allergic reactions.

The benefits of silk for
body and soul

If you continuously wear your silk boxer brief, your skin will feel noticeably smoother within 30 days. The silk fiber has a softening, renewing effect on your skin because of the protein ‘sericin’, which is found in silk. When wearing your cotton boxerbrief, the silk forms a barrier layer, helping retain moisture whilst simultaneously having a plumping, anti-keratinizing, anti-wrinkle effect.

Silk boxer brief for the
optimal protection

Silk feels smooth, however, the material itself is very robust and will last for years. The smooth feel of silk ensures that the mens boxerbrief doesn’t overly excite the nerve endings. This also doesn’t result in discomfort in the form of itchiness and sensitivity.

Originated in
the Netherlands

Ynside (phonetic: “ien siede”) actually consists of two Frisian words (Yn and side) relating to our founders’ birth ground. They literally mean “in silk” and acts as the starting point of deep insights unlocking a passion for craftsmanship and sports.

Handcrafted boxerbrief in

All Ynside underwear, like the mens boxer brief, is handcrafted in Germany. In this way, we can ensure the highest boxer brief quality possible whilst at the same time keeping an eye on production and environmental factors.
